Gas prices in Utah: Rocky Mountain average and state gas tax

The EIA doesn't publish a weekly gas price for Utah on its own, so the closest official figure is the Rocky Mountain average: $4.46 a gallon for regular in the week of October 26, 2026, −1.0¢ from the week before. On top of the pump price, Utah charges 38.6¢ a gallon in state gas taxes and fees, 14th highest of 51. Add the federal 18.4¢ and taxes come to 57.0¢ a gallon, roughly 13% of the average price shown here.
